The following is a description of the sticker on Apple's official developer site.

Stickers

Stickers offer a fun, engaging way for people to express themselves in a Messages conversation without typing or using emojis. A sticker is an image or an animation that can be sent or placed on messages, photos, and other stickers to add emphasis and communicate emotion.

Design for expressiveness. People use stickers to visually convey moods and reactions. Strive to deliver stickers that connect with people at an emotional level. Consider incorporating imagery, words, and phrases to add new dimensions to conversations.

Think globally. Messaging is a universal form of communication. Aim for stickers that have broad, international appeal.

Add vitality through animation. Although stickers can be static images, animated stickers are a great way to impart energy in a conversation. Be sure to use a frame rate high enough to keep motion fluid.

Test placement possibilities. Users can scale, rotate, and place stickers over parts of a conversation. Make sure your stickers are legible against different colors and imagery, regardless of their position or size.

Sticker Formats

iMessage App and Sticker Pack Icons

Keep the background simple and provide a single focus point. Design an icon with a single, centered point that captures attention at a glance. Include a simple background that doesn’t overpower other icons.
